y3 claims.

This invention relates to 'an indicator or calendar and more particularly to a device to indicate a predetermined date in the month following that in which the device is set, such as indicating the menstruation dates for women, or other purposes where it is desired to calculate upon what day of the following month a predetermined number of days will fall from a certain date in the current month, taking into consideration the months that have twenty-eight, thirty and thirty-one days.

The object of the invention is to provide a device of this kind that shall be compact to fit into the pocket book and have the outward appearance of a compact.

Another object of the invention is to provide such a device that is simple of operation and reliable in action.

Another object being to provide an article that shall be cheap to make and durable, having few parts and simple in construction.

While this invention is primarily intended for use by women to calculate and keep track of their menstruation periods, it may be used for other purposes as well. In the present method of employing the conventional calendar and counting the correct number of days from the present period, mistakes can be made on account of the different numbers of days in the several months, while with my device no mistake can be made and the counting is automatic giving the result at a glance.

With these and other objects in view, my invention consists in certain new and useful construction and combination of parts as will hereinafter be fully described and claimed, and further illustrated in the accompanying drawing which forms a part hereof and in which like figures of reference refer to corresponding parts in all of the views, and it is understood that slight changes may be made without departing from the spirit of the invention.

In the drawing:

Figure 1 is a bottom view of the device and sho-ws the window for exposing the figures on the 30 day chart.

Figure 2 is an edge View of the same and shows the Window for exposing the figures of the 31 day chart.

Figure 3 is a top view of the device and shows the window for exposing the figures of the 28 day chart, and also shows the finger knob for operating the device.

Figure 4 is an enlarged cross sectional View of the device to clearly show the construction and combination of parts therein.

Figure 5 is a sectional view taken on the line 5-5 of Figure 4.

Figure 6 is a similar sectional View taken on the line 6 6 of Figure 4.

Figure '7 is an enlarged detail view of the lower face of the finger knob or clutch member.

Referring to the drawing:

The device comprises a two part casing similar to a ladies compact and composed of the bottom part I and the upper part I I which are retained together due-to a press fit. y

The bottom part I of the 'casing is formed with a V-shaped window I3 the sides of which project inward as shown.

The upper part I I is formed with a similar window I and a central fianged bearing opening I2; while in the side wall of the bottom part I0 is formed another window I4.

Rotatably mounted within the flanged bearing I2 is a combined finger knob and clutch member 24 which is formed on its lower face with the holes 25.

Within the casing thus formed by the parts I0 and II, is rotatably mounted a drum 2l] rigidly secured on a shaft It which is freely rotatably mounted in the finger knob 24 and in bearings in the upper tension spring 22 which is attached to the side of the drum 2II adjacent the hub Il and has projecting therefrom the clutch pins 23 for engagement by the holes 25 of said nger knob clutch 24 as the same is pressed inward against the action of the spring 34; and the lower tension spring 2l, the arms of which fit tightly into the lower part of the casing II).

Upon the face I8 of the drum 20 is a single row of figures 33, in red and runs from 1 to- 28 inclusive and is for a month of 28 days, and in the use of this chart, if the period date falls on the first of February, it is due again on the first of March, and so on, if the th, of February, then the 10th of March.

The face I9 of the drum 2i) is provided with two rows of figures; the outer row 3| being printed in black and the inner row 32 in red, and this is known as the 30 day chart, and is so arranged that the date of the present period is indicated by the black figures and the due date for the next month by the adjacent red figure; the drum 20 being rotated by the clutch knob 24 until the 4desired black figure shows in the window I3; the red figure also being exposed at the same time, being the due date for the next month.

The periphery of the drum 20 is divided by the line 28, and upon one side of said line are Y placed the black figures 29 and upon the. other side of the line 28 the corresponding red figures 30; this being known as the 31 day chart, to be operated in the same manner as the two other charts.

The black figure being turned to indicate the lpresent period date, using either the 30 or 31 day chart as the case may be, and the adjacent red figure will indicate the period due date for the next month, except in the case of a 28 day month, where only one row of figures is required.

It is also to be noted that the sides of the Windows I3, I4 and I5 are extended inward to within a short space of the drum 20 so that only those figures that are directly in register with the Windows Will be exposed therethrough.

Having thus described my invention7 what I claim as new and desire to secure by Letters Patent, is:

1. In a device of the class described, comprising a circular casing formed with a Window in each Vof its sides and in its periphery, a drum rotatably mounted within said casing under tension and means for rotating the same, a single row of figures from 1 to 28 inclusive to indicate a month having 28 .days marked upon one side of said'drum for Yexposure one at a time through the Window in that side of said casing, a double row or figures marked on the other side of the drum and exposed in pairs through the Window in the adjacent side of the casing, one set of' figures representing a month of 30 days and the gures in the other row, a month of 31 days and a. double row of figures marked on the periphery of the vdrum for exposure in pairs through the window in the periphery of the casing.

2. In a device of the class described, comprising a circular casing having tWo sides and an edge, each of said sides and edge formed with opening therein, a transverse shaft rotatably mounted within said casing with one end projecting from one of said sides, a drum rigidly secured on said shaft, tension springs mounted in said casing between said drum and the sides of the casing forvnormally holding said drum under tension, characters carried by the sides and edge of said drum adapted to be brought into registry with said openings as the drum is rotated, and means attached to said shaft for rotating said drum within the casing.

3. In a device of the class described, comprising a circular casing having two sides and an edge, said sides and edge formed with openings therein, a shaft rotatably mounted within said casing, a clutch member mounted on said shaft, a finger operated clutch member mounted Within one side of said casing, a spring for normally holding said clutch member out of engagement with the clutch member on the shaft, tension spring mounted within said casing for holding said drum under tension, and characters carried by said drum adapted to be exposed through said openings as the drum is rotated.
